MIETHOD OF MAKING DISPLAY SHEETS.

y Application led May 5,

This invention relates to improvements in advertising and other displaydevices and the method of making the same.V

An object of the invention is to provide a display sheet which may beutilized for advertising purposes and produced at aminimum cost, andwherein a corrugated surface of the sheet has indicia applied thereto,such` as a design, pictorial representation, or other suitable data, andwhichl sheet is adapted for arrangement in display Windows, as counteror pillar trims, Wall friezes and the like, in such manner that theindicia thereon will be legible from all angles of vision.

Another object is t0 apply indicia in distorted form to a surface of afoundation sheet and thereafter alter the configuration of said surfacein such manner that the indicia will be restored to its natural ornormal condition.

A further object resides in placing a de-l sign upon a sheet of materialwhich is then stretched to distort said design, whereupon the latter istransferred in its distorted form to a foundation sheet Which is thencorrugated to restore the design to its normal appearance. 2

The above and other objects will appear more clearly from thefollowingtdetail description, when taken inconnection with theaccompanying drawings, which. illustrate a preferred embodiment of theinventive idea. Y'

In the drawings- Figure l is a vfragmentary plan view of a sheetillustrating the first. step in the method;

Figure 2 is'a ,similar view of said sheet showing the design thereon indistorted form;

Figure 3 is a plan view illustrating the design transferred in distortedform to the foundation sheet;

Figure 4' is a similar view of the sheet illustrated in Figure 8afterthe same is corrugated; and l Figure 5 is a longitudinal section 0fFigure 4.

In carrying out the present method a. sheet of material 6, preferablvtranslucent land having elastic qualities, such as crepe paper, issecured in an unstretched condition to a frame of any desiredconstruction which may be adjusted in length and width for a purposewhich will presently appear.

2, by adjusting the frame to which the sheet is secured therebyvdistorting the design,' as

indicated. The sheet 6 is stretched longitudinally when the corrugationsin the foundation sheet upon which the design is ultimatel; placedextend transversely or vertically of t e sheet. but it will beunderstood that if these corrugations are to run longitudinally of thefoundation sheet, the sheet 6 should be stretched transversely or yertically by proper adjustment of the frame so as to distort the design in adirection at right' angles to that shown in Figure 2. It has been foundin actual practice that the sheet 6 should be stretched to increase itslength from about forty-five to fifty per (ent, but the amount ofstretching is dependent upon the size or width of the corrugations madein the foundation sheet. `For example, ifk the sheet`6 is normallythirty-six inches in length the same, after being stretched', should beapproximately fifty-two inches long. v The proper amount of` stretchingmay be readily accomplished by providing the frame upon which the sheet6 is mounted with a suitable scale.

After the tracing and stretching operation of the sheet 6 is performed asheet of ordina-ry tracing paper or the like is laid upon the sheet 6and pressure is applied to 'said` sheets, by rubbing or otherwise, totransfer.

the outlined design from the sheet 6 to the tracing paper, this transferbeing made possible by the use of soft crayon in the origlnal tracing.The design now appears on the tracing sheet in a reversed position andis now heavily outlined to make the same distinct. After this is donethe outline of the design is again transferred toanother sheet, suchV asa sketch board, by tracing over the design onlsaid tracing sheet and thedesign may` then be completely filled in in ink, as shown in thedrawings.

By ordinary lithographing or printing its distorted condition to thefacing of the sheet 7 the latter is corrugated and the design will, as amatter of course, then extendl coincident with the contour of thecorrugations, or, in other words, over the ridges and into` thejfurrowsof the foundation sheet. In so doing the design will be restored to itsnormal or original appearance, as shown in Figure 4.

In actual practice the foundation sheet 7 may be made up of a pluralityof units hav-` j ing repeats of the desired design thereon so that aroll of the sheet, for instance one thousand yards in length, may beprepared. This will'enable any particular advertiser, for example, toorder any desired length of the 4product and permit him to divide thesame into suitable lengths for display purposes in various places, suchas show windows. pillar or counter trims, wall friezes vand thelike. Inorder to prepare a length of the product such as described, a pluralityof foundation sheets or units 7, in their normal o1' flat condition, areprepared and each unit is of substantially the same length and Width asthe sheet 6 in its stretched condition. After the design has beentransposed to the flat units 7, the latter are properly trimmed` andplaced with adjacent ends overlapping so as to register any parts of thedesign extending to the ends of the units with similar parts of saiddesign on adjacent units; and the overlapped ends are then gluedtogether and compressed so that said units will combine to form onecontinuous strip. Said strip is then rolled up and fed into acorrugat-ing machine to corrugate the surface carrying t e design.

It will, of course, be understood that various methods may be employedfor transferring the design in its distorted form on to the flat surfaceof thefoundation sheet 7. For instance, instead of securing on tracingpaper an impression of the distorted design from the sheet 6 andultimately transferring said design. onto sketch board for lithographingor printing purposes in the manner set forth, it may be possible totrace the design directly onto the sketch board Aand thereby eliminateintermediate steps in the lmethod. f
